Cooper Wheelock < Support < Technical Support FAQ's      Cooper Wheelock Support Support:  Technical Support FAQ's TESAN-Tech Support Engineering App Notices Computer Software Tools Online Calculators Sound Clips Product Cross Reference Contact Technical Support Documentation Center - All Documentation Center - Discontinued  Technical Support Frequently Asked Questions      Telephone Questions   QUESTION   ANSWER 1. "What High Candlepower TeleStrobe do I use with an analog phone system with 110 VAC power cord?" PS-11A-WPW         2. "What Ringer do I use with an analog phone?"   UTA-1         3. "I need a signal device for a digital phone system."   Cooper Wheelock does not have a device that is plug and play with a digital system but if you can provide a dry contact when the phone rings we have a interface (DCI-24-24) that will receive the contact closure and provide a 24vdc output that can be used with a number of products like a UTA-1         4. "I need a weather Resistant Telephone signal device."   Either the UTA-1 or the TB-593 for analog phone systems.         5. "I am installing a digital phone system for my customer and he wants a signal device for his guys in the warehouse. The system can provide a contact closure when the phone rings.  What would be the loudest horn you make?"   The MTH-24 would be the best device for this installation. It comes with its own power supply and activates on a contact closure.         6. "I have a CA-312 that was working but I moved its location and now it does not operate even though I measure ring voltage coming into the device."   The common problem with this device is they require a good ground. If you place your butt set on tip and ground and do not pull dial tone, this would verify that the ground is not correct. Make sure you have a solid earth ground         7. "I am installing the UTA-WH-VPS. Where can I get the 110-power that I need?"   The 110 VAC comes from any standard wall outlet. Simply cut a line cord and connect to TB3 and plug into the wall.         8. "I want to install a chime for my phone system. Need something small that I can leave on my desk. Any suggestions?"   The CH-AT1-W works directly off the phone ring voltage and is small enough to leave on your desk.         9. "My customer is calling me looking for a loud horn for his garage. He currently has an old Cooper Wheelock bell on the wall but I can’t seem to find it in your catalog. What would be the replacement?"   The bell you are referring to is probably a Series 163 Bell. The recommended replacement would be a MTH-24, which is 117dB, and a CRT-T-40 which is the relay to activate the horn.         10. "I am trying to get the UTA-WH-VPS to operate on my analog phone no matter what phone I try the thing won’t ring. What is the issue?"   That unit requires a 115vac wired directly to TB3 on the unit.         11. "My customer has called me to fix his PS-33A-WPW because it won’t stop flashing on his analog phone line. Do you have any suggestions?"   The unit is working fine. The problem is the unit is not the right product for the application. That device requires 18-30 volts AC or DC. The device you need is either the PS-11a-WPW, which also needs to be plugged into a 110 VAC wall outlet, or the PS-15a-WPW, which can connect directly to the analog phone line.   Appliances QUESTION ANSWER 1. "I need a horn that can take a pulse voltage from my FACP"   MT-12/24-R         2. "I need a Horn Strobe that I can put in a freezer"   Use the ASWP-2475W-FR with the WPBB-R Back Box         3. "Do you make a strobe only appliance for outdoor use that can be synchronized?"   Yes, the RSSWP-2475W-FR with the WPSBB-R Back Box         4. "Do you have a Horn Strobe that operates on 115 VAC ?"   Yes, the MT4-115-WH-VFR with the WBB-R Back Box         5. "I am synchronizing using a Cooper Wheelock Synchronization module (SM-12/24 and/or DSM-12/24) and using Series AS, NS and RSS appliances.  My audible chirped once then shut off."   Check the audible connections on the sync module for proper polarity.  In addition check the audible connections for both forward polarity during alarm.  Ensure that voltage is not a pulsed voltage such as a temporal pattern or march time.         6. How do I set either the NS or the AS appliances for continuous horn operation?"   Remove the factory installed jumper from the Code 3 position.  Note that you cannot get continuous horn when connected to a sync module.         7. "I have the CH 70 Chime Strobe and I want to use it with a Sync /module."   Wire the strobe portion of the Chime Strobe through the Sync Module. Wire the Chime portion through your FACP on a separate NAC Circuit and set the Chime to single stroke and pulse the NAC Circuit.         8. "How do I set the DIP switches for Code 3 on a MT-12/24-R?"   By setting the SW 1 DIP switch. Position 1 sets the dB level from either high or low. Positions 2 through 4 sets the priorities of the signal. Systems << Back To Top QUESTION ANSWER 1. "I have several strobes on my NAC Circuit from my FACP which is rated at 1 AMP. I want to put more horn strobes on that circuit. How can I accomplish this?"   By using the PS-8 Power Booster         2. "I have 4 circuits of Horn Strobes that I need to synchronize. Do you have a product I can use?"   Yes, either the PS-8 Power Booster or two interconnected DSM Sync Modules         3. " I would like to parallel two of the outputs on the PS-8 Power Booster to give me a 4 Amp output"   Cooper Wheelock no longer manufacturers amplifiers.         4. How do I connect multiple PS-8 Power Boosters with Class "B" wiring without the silence option?"   Wire to Input 1, Then come out of output 4 to the input 1 of the next booster and set the DIP switch according to the Instruction Manual.         5. "How many messages can I have on the SAFEPATH?"   The SAFEPATH is shipped with 8 standard messages         6. "Am I able to use your SAFEPATH to power my paging speaker system that I already have installed?"   No. You can not use standard paging speakers on the SAFEPATH because the speakers have to be designed to work with supervisory circuits. Standard speakers do not have the circuitry required for supervision.         7. "Instead of messages can I have tones from my SAFEPATH?"   Yes. Cooper Wheelock will program the chip set (PMK) with the tones you require.         8. "Can your SAFEPATH be used as a paging system as well as voice evacuation?"   Yes. This unit can be used for all call telephone paging with no other equipment. If zone paging is required the sp4-tzc and sp4-aps need to be installed         9. "Can I also use the SAFEPATH for weather alerts as well as fire?"   Yes. It is just a matter of activating the contact input on the voice message board. You must have that message recorded on the unit.         10. "Will the SAFEPATH work with 25 or 70.7-volt speakers?"   Yes. It will work with both 25v and 70v speakers providing they are supervisable.         11. "Am I able to wire multiple PS-8's to the SAFEPATH and have them all sync together?"   Yes. All you have to do is set the SAFEPATH for the sync output and configure the supplies for follower mode         12. "When I hook a NAC/24vdc to the SafePath inputs it doesn’t play the message, only tones."   The SafePath is only activated from a dry contact closure (a short). If your FACP cannot provide a contact closure and will only give a voltage output then you need to order a Cooper Wheelock model # NACIM  (Notification Appliance Circuit Interface Module). This module will take your FACP’s voltage output and convert it to a signal for activation of the SafePath.         13. "Do you have a flush mount kit for the SafePath?"   No. The unit is designed for surface mount only.         14. Do the batteries fit inside of the SafePath?"   SAFEPATH will fit up to two (2) 12 ah batteries.         15. "Can I change the SMK messages after installing the SAFEPATH system at my job location if the customer wants special messages later?"   Yes. All you need to do is order an AM- SP40s-PMK         16. "We just installed a remote microphone station to my SAFEPATH but it doesn't work."   Make sure SW 6 is set to CC and the input jumper is set for 1 volt         17. "Where are the conduit entrances located on the SafePath?"   Conduit entrances are on the top and and both sides of the enclosure.
